I was havin a little session on the plastic the other day and my finger tips started to feel really 'smooth'. I felt like I was losing friction and blowing off stuff that I was sticking before. Anybody experience this? Know a way to fix it?

You may have answered your own question up there...You might want to get the holds a litle caked with chalk, and ease up the texture with a little sand paper. Or use some super glue on your tips if you cant do the things I listed.

Here is anouther Idea that I am looking into, concrete climbing holds, check out this site: http://users.penn.com/~petro/index.html they make holds out of sandstone and granite, mixtures. Rock is supposted to not burn away your skin like plastic.
